On Friday 15 May 2026, Luxembourg’s Ministry of Mobility and Public Works announced that the Government Council has approved the draft law relating to the financing of the Alzingen bypass construction project.
Luxembourg’s Mobility and Public Works Minister Yuriko Backes stated that Hesperange and the surrounding area had suffered from heavy traffic for too long, with around 20,000 vehicles passing through residential districts every day. Included in the National Mobility Plan (PNM) 2035, the Alzingen bypass aims to redirect transit traffic from the N3 road onto the future bypass route, noted the ministry.
The project is expected to reduce congestion within the locality and free up public space for sustainable mobility by redirecting part of the regional traffic. The plans also include modal filters and the development of a shared space to calm traffic in Hesperange town centre and encourage public transport, cycling and walking.
According to the ministry, the government’s approval allows the legislative procedure for the project to begin.
The provisional timetable foresees the adoption of the financing law and the completion of studies, followed by land acquisitions, technical analyses and the obtaining of the necessary permits. The environmental and renaturation aspects, which form a central part of the project, require strict procedures as well as the gradual implementation of compensatory measures and specific works. Authorities expect to complete these by 2032 before major construction works on the bypass can begin in sensitive areas. Completion of the bypass is scheduled for the end of 2037.
The bypass project is also subject to significant environmental requirements. In particular, it depends on adapting the national protected area “Réiserbann” and renaturing the Alzette river and its tributaries.
The renaturation works must take place before construction begins in the Alzette valley. These measures include creating habitats favourable for breeding, resting and feeding, particularly for species located within the protected Natura 2000 area “Upper Alzette Valley (LU0002007)”, as well as appropriate land management following renaturation.
The draft law provides for a total budget of €390 million, said the ministry.
